I don't know where to go now with my 3.5 year old. He has always been very strong willed but I am wondering if it is more than this now. He was the perfect baby, very content but alway really into everything and really advanced. Once he got to a toddler he got the terible two's but really extreme. He seemed to be getting better from this but recently his behaviour has got so extreme. He will be good as gold one minute then I can see the switch, it's like something just goes and he become an awful child, doing anything he can to get in trouble. He will push people over, throw things about, rip things, anything he can think of and the worst thing is it all done with a smirk and when you try to discipline him he will just laugh. Some time he will cry but then crack up laughing a few seconds later. The more he is in trouble the better he likes it. I just don't know why he would want to be in this situation. I've got to the point where I feel like he could give me a breakdown, I just don't know how to stop this. I've tried really praising his good behavior, ignoring bad behaviour, time outs, reward charts and now I've got to the point whare I am constatntly shouting and I've never wanted to be that kind of mum. I try to give him as much attention as I can and we have loads of trips out, I know it sounds like attention seeking but I really do believe I give him plenty. He is very intelligent he knew colours and shapes as he turned 2 and now recognises numbers 1-20 and his ABC and he can be really quite devious when he wants to be. Other things that have concerned me are he copies other children, I know this is normal but he does it a lot and doesn't seem to realise he will start annoying the other child getting really in their face. He will also just completely ignore people sometimes, it's like speaking to a brick wall and I know this is a sympton of Autism. The thing is he can be so good and so many people say he seems like he's well behaved it's like he can just turn it on. His nursery teacher has also said she has concerns about him too but wouldn't go any further than that and tell me what she think it may be. She has said give it a few more months and see how he goes. Any suggestions would be great as i really need to try to get our family back on track, I have a 1 year old too and don't want his behaviour to start rubbing off on him.
